실내 표면온도 측정 방법에 따른 평균복사온도 도출

초록

Among the physical variables regarding thermal conditions and heat stress, the determination of mean radiant temperature is a classic problem in the thermal environmental field. This study deals with the methods of calculating mean radiant temperature using surface temperatures and angle factors. Two measurement methods using contact thermometer (CT method) and infrared thermographic camera (IR method) have been applied for measuring indoor surface temperatures. The measurement has shown that the difference in surface temperature of the blinds measured by two methods have increased with a high difference of about 5°C. The result of the study reports that it is indecated that the method using a infrared thermographic camera is suitable in order to accurately derive the mean radiant temperature.
